To all whom it may com-em:

Be it known that 1, ANTHONY L. Visser, a citizen of the `United Statesof America, residing at Bridgeville, in the county of Allegheny andState of Pennsylvania, have invented certain new and useful Improvementsin Railway-Frogs, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to railway frogs and more particularly to thattype disclosed in my prior Patents No. 912,049 granted February 9th,1909 and No. 940,560 granted November 16th, 1909.

The primary object of my invention is to provide a frog with a movableblock for controlling the passage over rails'converging at the frog, themovable block being constructed to provide a strong and durablestructure that insures a safe passage of heavy rolling stock over thefrog.

Another object of this invention is to provide a movable frog block thatcan be shifted simultaneously with a switch mechanism, including asignal, the frog block being arranged whereby it can not becomeaccidentally displaced during the passage of rolling stock over thesame.

A further object of this invention is to provide a frog block that canbe repeatedly adjusted to compensate for wear.

With the above and other objects in view, the invention resides in thenovel construc tion, combination and arrangement of parts to behereinafter specilically described and then claimed.

Reference will now be had to the draw ing, wherein like numerals ofreference designate corresponding parts throughout the several views, inwhich:

Figure 1 is a plan of a frog in accordance with this invention; Fig. 2is a longitudinal sectional view of the same; Fig. 3 is a perspectiveview of a bed plate; Fig. 4 is a perspective view of a detached guidestrap adapted to form part of the frog; Fig. 5 is a perspective view ofa detached brace or guard adapted to form part of the frog; Fig. 6 is aplan of a modified form of frog block; Fig. 7 is a plan of hinged gatesto facilitate removing dirt from the bed plate; Fig. 8 is a longitudinalsectional view of the same; Fig. 9 is a perspective view of an attachedgate; Fig. 10 is a perspective view of a keeper used in connection withthe gate;

and Fig. 11 is a perspective view of a detached stop.

The reference numerals 1 and 2 denote cross ties adapted to support abed plate 3, which is rectangular in plan. r1`his bed plate has the endsthereof provided with slots or openings 4 and 5 for the confronting endsof rails G and 7. The rails are supported by bottom plates 8 riveted tothe bed plate 3, and the ties 2 are cut away, as atl 9, to`provideclearance for the bottom plates 8.

The rails 7 are spaced apart by a block 11 arranged between the rails 7and secured thereto by tie bolts 12 and nuts 13. The cuter sides of therails 7 are braced by bars 14 bolted or otherwise connected, as at 15,to the bed pla te 3, the bolts having the heads thereof eountersunk inthe bars 14. Each bar has a depending tongue 1G extending from one endthereof to the opposite end, and this tongue is adapted to fit betweenthe outer base fianges of the rails 7 and the lon gitudinal edges 17 ofthe seat 5. The rails 8 are held by similar bars 18 bolted or otherwiseconnected to the bed plate 3, as at 19.

The bed plate 3, intermediate the ends thereof, is provided with sets oftransversely arranged slots 20 and 21, the set of slots 20 being locatedcentrally of the bed plate, while the slots 21 are at the outer edges ofthe bed plate with the outer edges of the slots open. The slots 21 areadapted to receive the vertical portions 22 of guide straps 23 bolted orotherwise connected to the bed plate, as at 24, said bolts extendingthrough openings 25 provided thereforl in the straps 23. The straps 23have guides 26 for the rectangular ends of bars 27 mounted in a frogplate 28. Those portions of the bars 27 within the frog 28 aredove-tailed, as at 29 and the dove-tailed portions are fixed within theblock by screw bolts or other fastening means 30 extending downwardlythrough the block. This manner of connecting the frog block 28 to thebars 27 prevents said bloclr from becoming accidentally displacedrelatively to said bars.

The frog block 28 has straight passages or grooves 31, adjacent to thelongitudinal edges thereof, and a diagonally disposed passage or groove32 between the passages or grooves 31. One of the grooves 31 and thegroove 32 coperate in controlling the passage of rolling stock from therails 6 to the rails 7 and after the side walls of these grooves havebeen worn, the block 28 can be reversed whereby the other groove 3l willcooperate with the groove 32. The frog block Q8 is provided withdepending lugs or pins 33 extending' into the slots 20, these lugslimiting the movement of the frog block upon the bed plat-e. To protectthe slots 9,0 and prevent foreign mat-ter, as coai dust, fromaccumulating in saidl slots, a cover plate is bolted or otherwisesecured, as at 35, to the under side of the bed plate 3, between theties l.

Mounted transversely of the frog block 28 is a bar 36 and this bar hasapertured ends, one of which is pivotally connected to an actuatinglever 37. The bar 36 extends through an opening provided therefor in theblock 28, without interfering with the passages or grooves 31 and 32.Any suitable switch or signal mechanism can be employed forsimultaneously shifting the frog block 28 with a switch tongue (notshown). rIhe bed plate 3 can be secured to the ties l and 2 by spikes 3Sor other fastening means.

In Fig. 6 of the drawings there is illustrated an inner wear frog block39, having a tongue 40 cooperating with the rails 7 in switching rollingstock. In lieu of the plate 34, I can use two gates 4l. These gates arehinged together, as at 42, beneath the frog block and each gate has agutter 43 provided with a drain opening 44. The frog block is providedwith depending keepers 45, and adapted to iit over these keepers arestraps 46 carried by the outer edges of the gates. Extending throughsaid straps and sait keepers are detachable rods 47, normally retainedin place by nuts 4S. The rods 47 have handles 49 whereby they can beeasily withdrawn to release the gates to deposit or dump the mattercontained within the gutters 43.

In Fig. ll there is illustrated an angle stop that can be secured to theunder side of the bed plate to extend upwardly through the slots 20, tolimit the movement of a frog block. The angle stop can be made ofvarious sizes whereby the frog block will have a desired amount ofmovement, and it is only necessary to change the angle stop when it isdesired tochange the Athrow or movement of a frog block.

what I claim is 1. In a frog block, a bed plate adapted to supportrails, al grooved block slidably mounted upon said plate between therails, guide bars arranged transversely ot said block, straps carried bysaid bed plate for guiding said bars and having vertical portionsinterlocked with the edges of said bed plate, means arranged beneathsaid block to limit the movement thereof, and a bed plate arranged upont-he underneath side of said bed plate and adapted to protect saidmeans.

2. In a frog block, a bed plate, a'grooved block slidably mounted uponsaid bed plate, straps having vertical portions Ainterlocked with theedges of said bed plate, and means carried by said block and extendinginto said straps to guide saidblock in its movement upon said plate.

3. In a frog block, a bed plate, a grooved block slidably mounted uponsaid bed plate, straps having vertical portions interlocked with theedges of said bed plate, means carried by said block and extending intosaid straps to guideV said block in its movement upon said plate, andmeans `arranged beneath said block and -adapted to limit the movement ofsaid block.

In testimony whereof I aiiiX my signature in the presence ot twowitnesses. ANTHONY L. VISSAT.
